  1. ^ a b c d e f g h This is the pinout for source-side connector, the sink-side connector pinout will have lanes 0–3 reversed in order; i.e., lane 3 will be on pin 1(n) and 3(p) while lane 0 will be on pin 10(n) and 12(p).
  2. ^ a b Pins 13 and 14 may either be directly connected to ground or connected to ground through a pulldown device.

DisplayPort (DP) is a digital display interface developed by a consortium of PC and chip manufacturers and standardized by the Video Electronics Standards Association (VESA). The interface is primarily used to connect a video source to a display device such as a computer monitor, and it can also carry audio, USB, and other forms of data.[1]

DisplayPort was designed to replace VGA, FPD-Link, and Digital Visual Interface (DVI). The interface is backward compatible with other interfaces, such as HDMI and DVI, through the use of either active or passive adapters.
